Schedules For Clinical Assessment In Neuropsychiatry Research Articles

The effect of the environment on symptom dimensions in the first episode of psychosis: a multilevel study.

The extent to which different symptom dimensions vary according to epidemiological factors associated with categorical definitions of first-episode psychosis (FEP) is unknown. We hypothesized that positive psychotic symptoms, including paranoid delusions and depressive symptoms, would be more prominent in more urban environments. We collected clinical and epidemiological data on 469 people with FEP (ICD-10 F10-F33) in two centres of the Aetiology and Ethnicity in Schizophrenia and Other Psychoses (AESOP) study: Southeast London and Nottinghamshire. We used multilevel regression models to examine neighbourhood-level and between-centre differences in five symptom dimensions (reality distortion, negative symptoms, manic symptoms, depressive symptoms and disorganization) underpinning Schedules for Clinical Assessment in Neuropsychiatry (SCAN) Item Group Checklist (IGC) symptoms. Delusions of persecution and reference, along with other individual IGC symptoms, were inspected for area-level variation. Reality distortion [estimated effect size (EES) 0.15, 95% confidence interval (CI) 0.06-0.24] and depressive symptoms (EES 0.21, 95% CI 0.07-0.34) were elevated in people with FEP living in more urban Southeast London but disorganized symptomatology was lower (EES -0.06, 95% CI -0.10 to -0.02), after controlling for confounders. Delusions of persecution were not associated with increased neighbourhood population density [adjusted odds ratio (aOR) 1.01, 95% CI 0.83-1.23], although an effect was observed for delusions of reference (aOR 1.41, 95% CI 1.12-1.77). Hallucinatory symptoms showed consistent elevation in more densely populated neighbourhoods (aOR 1.32, 95% CI 1.09-1.61). In people experiencing FEP, elevated levels of reality distortion and depressive symptoms were observed in more urban, densely populated neighbourhoods. No clear association was observed for paranoid delusions; hallucinations were consistently associated with increased population density. These results suggest that urban environments may affect the syndromal presentation of psychotic disorders.

Prevalence and socio-demographic risk factors associated with psychoactive substance use in psychiatric out-patients of a tertiary hospital in Nigeria.

Background:The co-morbidity of psychoactive substance use and other mental disorders is a major challenge to the management of both conditions in several parts of the world. There is relative dearth of information on co-morbidity and its predictors in Nigeria. This study determined the prevalence and socio-demographic risk factors associated with psychoactive substance use in the psychiatric out-patients of a tertiary hospital in Nigeria.Study Design:A cross-sectional study.Materials and Methods:From routine clinic visits over a 4-month period, each consecutive 4th adult patients (>18 years) who had previously attended the clinic at least for 1 year, completed a socio-demographic and semi-structured drug use questionnaires and interview with the Schedule for Clinical Assessment in Neuropsychiatry (SCAN) to generate substance use diagnosis. Data was analysed using the statistical package for social sciences (SPSS), version 16. Level of significance was set at P < 0.05.Results:The lifetime prevalence for the use of substance was 29.3%, while that for multiple substances was 17.7%. The most commonly used substances were alcohol, cannabis and tobacco and they were also the ones mostly used in combination with one or the other. A total of 10.1% of the patients had a psychoactive substance use disorder. Being male, married with at least primary education and unemployed were significant risk factors for substance use.Conclusion:Psychoactive substance is common among the psychiatric outpatients of the hospital with males, those with formal education, the married and unemployed being at high risk of substance use.

Diagnostic validity of the composite international diagnostic interview (CIDI) depression module in an East African population.

To evaluate the validity and reliability of the structured Composite International Diagnostic Interview (CIDI) in diagnosing current major depressive disorder (MDD) among East African adults. A sample of 926 patients attending a major referral hospital in Ethiopia participated in this diagnostic assessment study. We used a two-stage study design where participants were first interviewed using an Amharic version of the CIDI and a stratified random sample underwent a follow-up semi-structured clinical interview conducted by a psychiatrist, blinded to the screening results, using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) instrument. We tested construct validity by examining the association of the CIDI and World Health Organization Quality of Life (WHO-QOL) questionnaire. We calculated the psychometric properties of the CIDI using the SCAN diagnostic interview as a gold standard. We found that the Amharic version of the CIDI diagnostic interview has good internal reliability (Cronbach's alpha = 0.97) among Ethiopian adults. Compared to the SCAN reference standard, the CIDI had fair specificity (72.2%) but low sensitivity (51.0%). Our study provided evidence for unidimensionality of core depression screening questions on the CIDI interview with good factor loadings on a major core depressive factor. The Amharic language version of the CIDI had fair specificity and low sensitivity in detecting MDD compared with psychiatrist administered SCAN diagnosis. Our findings are generally consistent with prior studies. Use of fully structured interviews such as the CIDI for MDD diagnosis in clinical settings might lead to under-detection of DSM-IV MDD.

Psychiatric morbidity in stroke patients attending a neurology clinic in Nigeria

Stroke produces a wide range of mental and emotional disorders. Neuropsychiatric complications associated with stroke may have negative effects on the social functioning, overall quality of life and the recovery of motor functioning of stroke survivors. To determine the prevalence and nature of psychiatric morbidity among stroke patients attending neurology outpatient clinic of the University of Ilorin Teaching Hospital (UITH), Ilorin-Nigeria. All patients with stroke aged 18 years and above at an outpatient neurology clinic in Ilorin, Nigeria were assessed for mental and emotional disorders using the Schedule for Clinical Assessment in Neuropsychiatry (SCAN) over one year (March 2009 to February 2010). Overall prevalence of psychiatric morbidity was 36.0% (30/83) among 83 patients who constituted the study population. Specific diagnoses recorded were depression (19.2%), generalised anxiety disorder (9.6%), harmful alcohol use (2.4%); dementia, somatoform disorder, phobia and delusional disorder each had a prevalence of 1.2%. Clinical and sociodemographic variables were not significantly associated with psychiatric morbidity. Psychiatric disorders are often associated with stroke. Identifying and treating stroke patients with these psychiatric co-morbidities could thus help to improve the overall quality of life of these patients.

A prospective latent analysis study of Axis I psychiatric co-morbidity of DSM-IV major depressive disorder

We tested the degree to which longitudinal observations fit two hypotheses of psychiatric co-morbidity in DSM-IV major depressive disorder (MDD) among adult patients: (1) Axis I co-morbidity is dependent on major depressive episode (MDE) course, and (2) Axis I co-morbidity is independent of MDE course. In the Vantaa Depression Study (VDS), 269 psychiatric secondary-care patients with a DSM-IV MDD were evaluated with the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) at intake and at 6 and 18 months. Three evaluations of co-morbidity were available for 193 out of 259 living patients (75%). A latent curve model (LCM) was used to examine individual-level changes in depressive and anxiety symptoms across time. Outcome of MDD was modeled in terms of categorical DSM-IV diagnosis and Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HAMD) scores, and co-morbidity in terms of categorical DSM-IV anxiety and alcohol use disorder (AUD) diagnoses and Beck Anxiety Inventory (BAI) scores. Depression and anxiety correlated cross-sectionally at baseline. Longitudinally, changes in depression and anxiety correlated in both the 0-6 and 6-18 months time windows. Higher baseline depression raised the likelihood of an AUD at 6 months, and patients with more depressive symptoms in the 0-6 months time window were more likely to have had an AUD at 6 months, which further linked to less improvement in depression symptoms in the 6-18 months time window. Longitudinal and individual-level courses of both internalizing and externalizing disorders in adult patients with MDD seem to be dependent, albeit to differing degrees, on the course of depressive symptoms.

Toward integration of palliative care into cancer care: A study on profile of psychosocial and clinical complications among attendees of a Nigerian oncological center.

e20675 Background: The integration of palliative care into cancer management is abysmal in this context and paucity of empirical evidence constitutes constraint for policy formulation and their translation into cancer care. This study assessed psychosocial and clinical complications among Nigerian cancer subjects. We postulated the interplay of psychosocial and clinical factors would constitute evidence for palliative care. Methods: This is an observational study among 200 adult participants with histological diagnosis of cancer recruited using systematic random sampling. Eligible participants were interviewed by the researchers using socio-demographic/clinical profile questionnaire, Centre for Epidemiological Studies Depression Scale Revised (CES-DR) and Schedule for Clinical Assessment in Neuropsychiatry (SCAN). Data analyses were done using SPSS-15. Results: The commonest type of malignancy was breast cancer (51.0%); cervical cancer 29.5%, colorectal and prostatic cancers were 10.5% and 9.0% respectively. Slightly less than half (49.0%) of subjects had advanced cancer. Most subjects (36.5%) had symptoms for over a year at presentation. Two-thirds (66.0%) had pain, 52% had weight loss and 20.0% had external ulcer. Ninety-eight (49.0%) subjects had depressive symptomatology (CES-DR score ≥16), while prevalence of depression based on SCAN was 27.5%. Depression was significantly associated with higher educational status (p=0.003), unemployment (p=Ÿ0.004), unmarried status (p=0.004), advanced cancer stage (p=0.006), longer duration of cancer (p=0.048), pain (p&lt;0.001), physical complications (p&lt;0.001). However, unmarried status, unemployment, pain and duration of cancer still correlated with depression following logistic regression. Conclusions: In this study, preponderance of physical, psychosocial complications, advanced stage illness and high symptoms burden suggest that integration of palliative care into cancer management should be the rule rather than exception. Lastly, further research on palliative care with translation of resulting research based evidence into cancer care is implied.

Screening for depression with Centre for Epidemiological Studies Depression Scale Revised and its implication for consultation–liaison psychiatry practice among cancer subjects: a perspective from a developing country

Co-morbidity of depressive symptomatology is a common indication for use of mental health services in oncology. In this regard, screening instruments are useful for prompt identification of mental disorders in cancer. This study is set to evaluate the diagnostic validity of Centre for Epidemiological Studies Depression Scale Revised (CES-DR) for depression screening in cancer. The CES-DR and the Schedule for Clinical Assessment in Neuropsychiatry (SCAN) were administered by the researchers on 200 attendees of a Nigerian hospital with histological diagnoses of cancer. Subsequently, the diagnostic validity of CES-DR was compared with SCAN. Ninety-eight (49.0%) participants had significant depressive symptomatology (CES-DR scores of ≥ 16) as against the diagnosis of depression in 55 (27.5%) participants following SCAN interview. Furthermore, of these 55 (27.5%) depressed participants, two (3.6%) participants had CES-DR scores <16 (non-cases). The Cronbach's alpha reliability of CES-DR was 0.86, and sensitivity and specificity of CES-DR were 96.4% and 68.7%, respectively, whereas positive and negative predictive values of CES-DR were found to be 0.54 and 0.98, respectively, in this study. The average administration time of CES-DR was 6 (± 2) min, and an inter-rater reliability of 93.7% was observed. The CES-DR was found in this study to be a useful tool for screening for depression in cancer but with diagnostic limitation when compared with SCAN. The development as well as popularization of screening instrument(s) with improved diagnostic and administration property for prompt identification of mental disorders to improve consultation-liaison psychiatry services in cancer care is recommended. Furthermore, replication of similar research is warranted.

SEROTONIN TRANSPORTER LENGTH POLYMORPHISM, CHILDHOOD MALTREATMENT, AND CHRONIC DEPRESSION: A SPECIFIC GENE-ENVIRONMENT INTERACTION

Key questions about the interaction between the serotonin transporter length polymorphism (5-HTTLPR) and stress in the etiology of depression remain unresolved. We test the hypotheses that the interaction is restricted to childhood maltreatment (as opposed to stressful events in adulthood), and leads to chronic depressive episodes (as opposed to any onset of depression), using gold-standard assessments of childhood maltreatment, severe life events, chronic depression, and new depressive onsets. In a risk-enriched sample of 273 unrelated women, childhood maltreatment was retrospectively assessed with the Childhood Experience of Care and Abuse (CECA) interview and 5-HTTLPR was genotyped. A subset of 220 women was followed prospectively for 12 months with life events assessed with the Life Events and Difficulties (LEDS) interview. Any chronic episode of depression (12 months or longer) during adulthood and onset of a major depressive episode during a 12-month follow-up were established with the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) interview. The short alleles of 5-HTTLPR moderated the relationship between childhood maltreatment and chronic depression in adulthood, reflected in a significant gene-environment interaction (RD = 0.226, 95% CI: 0.076-0.376, P = .0032). 5-HTTLPR did not moderate the effects of either childhood maltreatment or severe life events on new depressive onsets. The short variant of the serotonin transporter gene specifically sensitizes to the effect of early-life experience of abuse or neglect on whether an adult depressive episode takes a chronic course. This interaction may be responsible for a substantial proportion of cases of chronic depression in the general population.

Factors associated with anxiety disorders among HIV-positive attendees of an HIV clinic in Lagos, Nigeria

Anxiety disorders (ADs) occurring in people living with HIV/AIDS (PLWHA) are often poorly identified in spite of the untold consequences that may result if not diagnosed and treated promptly. This study aimed to describe factors associated with ADs among PLWHA. Three hundred participants were administered sociodemographic/clinical profile questionnaires, and diagnoses of ADs were made using Schedule for Clinical Assessment in Neuropsychiatry (SCAN) based on International Classification of Diseases, 10th edition (ICD-10) criteria. In this study, 65 (21.7%) participants were diagnosed with ADs. A lack of family support, unemployment, younger mean age and being unmarried (P < 0.05) were factors associated with ADs in PLWHA; however, lack of family support (odds ratio [OR] = 0.458, 95% confidence interval [CI] = 0.254-0.827, P = 0.010), being unmarried (OR = 1.930, 95% CI = 1.046-3.560, P = 0.035) and unemployment (OR = 0.495, 95% CI = 0.264-0.926, P = 0.028) were the only factors that remained significant following logistic regression analysis. Prompt identification with active management of ADs and their associated factors among PLWHA are advocated. Further research on the risk factors for ADs is also warranted.

First-episode psychosis at the West Bologna Community Mental Health Centre: results of an 8-year prospective study

Research mostly conducted in the UK and northern Europe has established that there are high rates of first-episode psychosis (FEP) in large cities and immigrant populations; moreover, psychosis has been found to be associated with cannabis use and early trauma. The present study aimed to evaluate the incidence rate of FEP and the distribution of several risk factors (e.g. age, ethnicity, substance abuse) in Bologna, Italy. The Bologna FEP (BoFEP) study is an 8-year prospective study. All FEP patients, 18-64 years old, consecutively referred to the West Bologna Community Mental Health Centre (CMHC) from 2002 to 2009 were evaluated. Sociodemographic information, migration history and clinical data were collected through an ad-hoc schedule. Psychiatric diagnoses were recorded using the Schedule for Clinical Assessment of Neuropsychiatry (SCAN). The overall incidence rate (IR) in the BoFEP study was 16.4 per 100 000 person-years [95% confidence interval (CI) 13.9-18.9]. The incidence was higher in young people, men and migrants (MI). The IR of FEP found by the Bologna study is lower than that found by other European studies. However, as in other studies, the incidence was higher in certain groups. This heterogeneity has implications for policy and mental health service development, and for understanding the aetiology of psychosis.

An epidemiological study of mental disorders at Pune, Maharashtra

Background:The WHO Global Burden of Disease study estimates that mental and addictive disorders are among the most burdensome in the world, and their burden will increase over the next decades. The mental and behavioral disorders account for about 12% of the global burden of disease. However, these estimates and projections are based largely on literature review rather than cross-national epidemiological surveys. In India, little is known about the extent, severity and unmet need of treatment mental disorders. Thus, there was a need to carry out rigorously implemented general population surveys that estimate the prevalence of mental disorders among urban population at Pune, Maharashtra. The study attempted to address unmet need and to form a basis for formulating the mental health need of the community.Objective:The study was undertaken to estimate the lifetime prevalence and 12 month prevalence of specific mental disorders in urban population, socio-demographic correlates of mental disorders and to assess the service utilization in individuals with mental disorders.Materials and Methods:The study was undertaken among adults aged 18 years and above living in house hold and in geographical area of Pune , Maharashtra. A minimum sample of 3000 completed interviews was planned using representative probabilities to population size (PPS) sampling method which ensured equal probability for every eligible member. Data listing was obtained from Census Office from recent census of 2001 data. The face to face interviews were undertaken in homes using fully structured interview schedule of World Mental Health Survey Initiative duly revised Version of WHO- Composite International Diagnostic Interview (CIDI 3.0) by trained investigators. Clinical reappraisal was carried out using Schedules for Clinical Assessment in Neuropsychiatry (SCAN) among ten percent of diagnosed cases selected randomly. Data were entered into DDE (Blaize Software) and analyzed using SPSS software package.Results:Overall lifetime prevalence of mental disorders was found to be 5.03%.Rates among males (5.30%) were higher as compared to females (4.73%). Among the diagnostic group , depression(3.14%) was most prevalent followed by substance use disorder (1.39%) and panic disorder (0.86%). Overall 12 month prevalence of mental disorder was found to be 3.18% which was 3.47% among males and 2.85% among females. Prevalence of depression (1.75%) was the most 12-month mental disorder, followed by substance use mental disorder (0.99%) and panic disorder (0.69%).Lifetime and twelve month prevalence of any mental disorder was the highest among employed group, followed by home makers and depression was more among married, followed by separated/divorced/widowed group and the least in unmarried group in the study. Treatment gap due to low prescription received indicated the most of the ill person did not acknowledge their need for treatment or do not received the appropriate care.Conclusion:The figure of 5.03% prevalence of diagnosable psychiatric disorders in adult population points to the great need to increase the prevention strategies both at primary and secondary level to overcome the disability and economic loss to society due to mental disorders.

Five-year follow-up of a cohort of people with their first diabetic foot ulcer: the persistent effect of depression on mortality

Depressive disorders are associated with mortality within 18 months of presentation of diabetic foot ulcers (DFU). The main aim of this study was to determine whether depressive disorder is still associated with increased mortality in people with their first foot ulcer at 5 years. This is a 5-year follow-up of a cohort of 253 patients presenting with their first DFU. At baseline, the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) 2.1 was used to define those who met DSM-IV (Diagnostic and Statistical Manual 4th edition) criteria for depressive disorder. Cox regression analysis controlled for potential covariates: age, sex, marital status, socioeconomic status, smoking, mean HbA(1c), diabetes complications and ulcer severity. The main outcome was mortality at 5 years. The prevalence of DSM-IV depressive disorder at baseline was 32.2% (n = 82). There were 92 (36.4%) deaths over the 5 years of follow-up. In the Cox regression (n = 246), after adjusting for covariates, baseline DSM-IV depressive disorder was significantly associated with a twofold increased risk of mortality for any depressive episode (HR 2.09, 95% CI 1.34, 3.25), minor (HR 1.93, 95% CI 1.00, 3.74) or major depressive disorders (HR 2.18, 95% CI 1.31, 3.65), compared with patients who were not depressed. Depression is associated with a persistent twofold increased risk of mortality in people with their first DFU at 5 years.

A Controlled Study of Depression among Attendees of an Oncology Clinic in West Africa

Depression is commonly encountered among cancer patients and has been linked with grave consequences if not promptly treated. This study was set to determine the prevalence of depression in cancer patients. The samples were recruited using systematic random sampling and made up of 200 cancer patients and 200 age and sex matched controls that consented and met the inclusion criteria. The instruments used included: Socio-demographic and clinical profile questionnaire, Centre for Epidemiological Studies Depression Scale Revised (CES-DR), and the Schedule for Clinical Assessment in Neuropsychiatry (SCAN). The instruments were administered by the researchers on the subjects and controls, and data obtained were analyzed using SPSS-15. A larger proportion of cancer patients compared to controls had depressive symptomatology (CES-DR score of 16 and above) made up of 98 (49.0%) cancer patients compared to 40 (20.0%) controls, and the difference was statistically significant, p = < 0.001. Seventy-four (18.5%) subjects from the two groups had depressive disorder using SCAN. The prevalence of depression in cancer subjects was 27.5% with 9.5% in controls and the difference was statistically significant with p = < 0.001. A substantial proportion of cancer patients with depression, 36 (65.5%, n = 55), had moderate depression, 15 (27.3%, n = 55) were mildly depressed, and 7.2% (n = 55) had severe depression. A significant proportion of cancer patients had depression compared with the controls with acute medical conditions. Prompt identification and treatment of cancer, mental disorders like depression should be integrated into cancer care in this part of the world.

Depression underdiagnosis and the effects on quality of life in outpatients with HIV at a Nigerian university teaching hospital

The study aimed to determine the frequency of depressive disorder in a sample of patients with HIV and its level of underdiagnosis by attending physicians. The study also explored the effect of depressive disorder on the quality of life (QOL) of patients with HIV. A sociodemographic questionnaire was administered to patients with HIV attending a medical out-patient clinic at Ahmadu Bello University Teaching Hospital, central northern Nigeria. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to screen for depressive symptoms, and the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) was used to confirm the diagnosis of depressive disorder. The patients’ medical records were screened for documentation of depressive symptoms or previous treatment with antidepressants by an attending physician. The World Health Organization Quality of Life assessment short version (WHOQOL-BREF) was used to measure six domains of QOL. A total of 310 patients with HIV participated in the study; of these, 14.2% (n = 44) met the diagnostic criteria for depressive disorder, according to the International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10). All of these cases of depressive disorder had not been previously recognised by any attending physician. Of the 310 participants, 58 (18.7%) had a ‘poor’ score and 252 (81.3%) had an ‘average or above’ score for overall QOL. Of the 44 with depressive disorder, 28 (63.6%) were among those with a poor score for overall QOL. A fairly similar pattern was observed for all the other domains, with patients with depressive disorder accounting for greater proportions of the participants with poor domain scores. Thus, the authors found that depression is common but seldom clinically recognised in people with HIV, and that it is associated with a reduction in quality of life. Identifying and treating depression in patients with HIV will improve functioning and general wellbeing.

Axis I and II psychiatric disorders in patients with traumatic brain injury: A 12-month follow-up study

Objective: To evaluate the occurrence of axis I and II psychiatric disorders among patients with traumatic brain injury (TBI).Design: Prospective observational study. Forty-five adult patients, who had attended an emergency unit because of TBI, were recruited. At 12 months, 38 patients were interviewed.Measures: Psychiatric disorders were evaluated using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II).Results: Before TBI, the 12-month rate of axis I psychiatric disorders was relatively high (39.5%) and the rate of alcohol dependence was especially elevated (18.4%). During the 12 months after TBI, axis I disorders were found in 47.4% of subjects. Six patients (15.8%) were found to have a disorder with an onset after TBI. Of these, five patients had depressive disorders (13.2%). Almost one third of the subjects (29.0%) had personality disorders. Antisocial and obsessive-compulsive personality disorders were the most frequent (10.5%).Conclusions: Both axis I and II psychiatric disorders are common among patients with TBI. Alcohol dependence and personality disorders are prevalent in individuals prone to TBI, whereas depressive disorders typically develop after injury. Psychiatric disorders should be addressed in rehabilitation, as otherwise they will hinder the recovery after TBI.

Mental disorders, chronic conditions and psychological factors: A path analysis model for healthcare consumption in general practice

To explore potential individual determinants of healthcare utilization in primary care (PC) using a structural equation modelling approach. Atotal of 638 patients from five PC units were randomly selected. Mental disorders, psychological distress and other psychological factors were assessed with the 28-item General Health Questionnaire (GHQ-28) and the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Medical records and ICD-10 diagnosis were used to measure somatic morbidity. There is a negative relationship between the presence of mental disorders and psychological well-being (−0.74), and a negative relationship with use of health services (−0.25). Age has a positive and significant relationship with the presence of chronic diseases (0.49), which has a positive and significant relationship with limitation of daily activities (0.18). This limitation has a positive relationship with poor perception of health (0.57) and with psychological well-being (0.03). Findings confirm the existence of specific pathways in PC health use. Health service use depends on the patient's psychological well-being and on the presence of chronic medical conditions. Healthcare professionals need to pay attention to the comorbidity of mental disorders and chronic medical conditions in order to identify frequent attenders and to decrease the inappropriate use of healthcare services.

Schedules for clinical assessment in neuropsychiatry

The schedules for clinical assessment in neuropsychiatry (SCAN) is a set of instruments, supported by manuals, that aim to measure and classify the psychopathology of the major psychiatric disorders of adult life. SCAN has been developed by the World Health Organization over several years and is widely used, as evidenced by its translation into 35 or more languages. To achieve robust levels of validity and reliability, SCAN is intended for use only by clinicians who have undertaken training at a World Health Organization designated SCAN training centre. There are 21 of these designated SCAN training and reference centres worldwide, five of which are in the United Kingdom. I attended …

Adherence to highly active antiretroviral therapy in depressed patients with HIV/AIDS attending a Nigerian university teaching hospital clinic

To determine the prevalence of depressive disorder in patients with HIV/AIDS receiving HAART; to determine the effect of depressive disorder on adherence to antiretroviral therapy; and to determine the significance of the association. The study was conducted amongst outpatients of Ahmadu Bello University Teaching Hospital, Zaria. A sociodemographic and drug adherence questionnaire was administered. The Centre for Epidemiological Studies Depression Scale (CES-D) was used to screen for depressive symptoms while the Schedule for Clinical Assessment in Neuropsychiatry (SCAN) was used to confirm the diagnosis of depressive disorder. A total of 310 patients with HIV/AIDS receiving HAART participated in the study. 68.4% were female and the mean age was 35.5 (± 8.97 years). 37.4% had secondary education, while 27.1% had tertiary education. Sixty-six participants (21.3%) had significant depressive symptoms while 14.2% met ICD-10 diagnostic criteria for depressive disorder. Overall, 73% of participants had good adherence to HAART. 63.6% of participants with depressive disorder had poor adherence to HAART compared to 21.1% of participants without depressive disorder (p<0.05). Depressive disorder in patients with HIV/AIDS is associated with poor adherence to antiretroviral medication. Early identification and treatment of depression in such patients may improve antiretroviral medication adherence and treatment outcomes.

Exploring the apparent absence of psychosis amongst the Borana pastoralist community of Southern Ethiopia. A mixed method follow-up study

There are few reports of the prevalence of psychotic disorders among isolated population groups. Where present, variations in prevalence estimates raise questions about the validity of methods of case ascertainment in such settings. In a previous population-based survey of the Borana pastoralist community in Ethiopia using the Composite International Diagnostic Interview, no cases of schizophrenia were identified. In order to further explore this finding and investigate how serious mental disorder is conceptualized, we conducted focus group discussions with key members of the Borana pastoralist community. Subsequently, focus group participants were used as key informants to identify cases with possible psychotic disorder, based on their conceptualization. Cases identified by key informants were interviewed by a trained psychiatrist using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN), to confirm presence of disorder. Focus group discussions were subjected to thematic analysis. The incongruity between local and psychiatric concepts lay mainly in the fact that key informants described characteristics of marata ("madness") in terms of overt behavioural symptoms. Following the focus group discussions, participants identified eight individuals with schizophrenia and 13 with a psychotic mood disorder, confirmed through SCAN interview. Studies of psychotic disorders in such communities are likely to benefit from combining structured interviews with the key informant method.
